Iron River, Wisconsin
10.7 mapped river miles, draining 28 square miles, in the Bad Montreal basin watershed. No gauge stands in it; the nearest is 13.2 miles away, and what this page knows about its temperature is Wisconsin DNR's classification of the water itself.
50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands, breaking at 58, 64 and 70°F, that the app paints. Grey is water nobody has measured.
The nearest live reading
The nearest gauge is 13.2 miles away, at Tyler Forks River At Stricker Road Near Mellen, Wi — not a reading of this water, but of what the region is doing today.
The character of the water
The Bad Montreal basin's Iron River runs almost entirely through national forest: 10.75 miles inside the Chequamegon against 10.7 miles of mapped axis, which is the whole of it. Wisconsin DNR designates the water Class II and Class III, managed as wild supplemented and as stocked, and has typed 9.1 of its 11.64 NHD miles — 78 per cent — splitting 6.3 Cold against 2.8 Cool, though these files cannot say which end each class sits at. There is no gauge in it; the nearest is on the Namekagon, 27.8 miles away. The channel is 13.9 feet across at the median, third order, draining 28.29 square miles. Brush Creek comes in at river mile 6.5 and Edies Creek at 5.6.
Thermal classification
Wisconsin DNR's classification of this water, reach by reach. A class, not a temperature — no July mean, because none was measured here.
| Reach | Typed miles | Band | Wisconsin DNR type |
|---|---|---|---|
| RM 8.4–5.6 | 2.8 | cool | — |
| RM 5.6–0.0 | 6.3 | cold | — |
Wisconsin DNR has classified 9.1 of the 11.6 miles NHD carries for this stream — 78% of it. The typed water splits 6.3 mi cold, 2.8 mi cool. The untyped reaches are not warm water — they are water Wisconsin DNR's inventory does not reach, and the mile ranges above span only the reaches it does.

Wisconsin DNR classification
Wisconsin DNR classifies this water as Class II and Class III. More than one class appears because the classification changes along the river. The thermal bar above shows where. The management tier on those reaches is stocked, wild supplemented. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.

Species
Wisconsin DNR designates this as trout water — Class II, Class III — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
Hatches on this water
42 insects are recorded from northern Wisconsin, which is the region this river sits in. That is a claim about the region and not a survey of this stream: nobody has recorded which of them has been caught here. Open the river in the app and the hatch panel will narrow it to the ones whose temperature window today's reading is inside.
